The slope of the line is whatever number is multiplied on the x variable so just solve the equation for x to figure out the slope. Simplify the fraction to get the slope of -25. Learn how to write the slope formula from scratch and how to apply it to find the slope of a line from two points.
Round to the near-est hundredth.
In slope-intercept form m is the slope and b is the y-intercept. Give the slope of the regression line and interpret the slope as a rate. Find the slope using m y2-y1 x2-x1. Take the derivative of the original function and evaluate it at the given point.
